INDEX count not be created

Hi

 I could not create index on a table. It shows like this

Msg 208, Level 16, State 1, Procedure dba_trigger_log_db_events, Line 58
Invalid object name 'master.dbo.DBA_DB_DDL_Trigger_Event_Information'.

What might be the error . Please help me to solve and create the index

I am using sql server 2012 sp1 developer edition

Thanks & Regards Manoj
